I found atleast hour delay between source database and destination database.I ran below queries to find the issue.

It shows DELAY in CAPTURE , and DELAY in ENQUEUE seems to be same. But propagation delay is just 3 seconds.Does that mean, Issue could be with CAPTURE process taking time to scan the REDO logs ?Can someone guide me what to check next etc.. ?

The issue can be with capture process at source database or
It can be with apply process at destination database.
query dba_apply to check the status and error message of apply process at target database.
Sometimes it happens due to high CPU usage too.When the
CPU utilization is high,sometimes it results in high
latency.
